ABSTRACT:
An optical apparatus includes a signal output device which outputs an analog signal corresponding to a position of an operation member and a determination device which determines the position of the operation member in accordance with at least first and second determinations. In the first determination, the determination device determines the position of the operation member during movement of the operation member by comparing the analog signal of the signal output device with a plurality of predetermined values. In the second determination, the determination device determines the position of the operation member after the operation member has stopped by using a manner different from a manner of the first determination.
